Through Speed

Hi All

 

Little issue with my router. My through speed when connected to the router is only 193Mbps, yet when i plug the ethernet direct to my pc, i get 920Mbps.

 

Hope some one has some ideas please>

 

Thanks

    Additional information needed for clarity:

     

    What is the full model number of your router?  Look on the nameplate on the device.

     

    What is the full brand name and model number of your modem/ONT connected upstream of your router?  Look on the nameplate on the device.

     

    When your say your throughput when connected to the router, I presume you are talking about a Wi-Fi connection?

    If yes, what band are you connected to?  The 2.4 GHz band or the 5 GHz band?

     

    What device, brand name and model number, are you connected with when you measure your throughput?

     

    What application are you using to measure throughput?  Recommend using the Ookla stand alone application that does not use a web address or web browser.  Available from the playstores.

      Hi there

      The router (data plate uploaded) is connected to the modem (data plate uploaded) via a Cat8 cable. Yes I’m measuring internet speed using Ookla. I figured no point I’m measuring the WiFi till the hardwired connection is sorted.

        Your Sagemcom Model F3896LG-VMB is a combination modem/router.  Specifically, how it is configured is critical to the configuration and functionality of your R8000 Wi-Fi router.

         

        Are the throughput problems you are experiencing a new situation or are you just now configuring this network?

         

        Your R8000 router is in a cascade connection downstream from a combination modem/router.  This results in a situation called double NAT which can cause lots of problems.  See here for reference:  https://kb.netgear.com/30186/What-is-double-NAT-and-why-is-it-bad.

         

        You need to find out how your Sagemcom device is configured and then decide on how you want to configure your R8000.  You may have to find a manual for instructions on your Sagemcom device.

         

        If your Sagemcom device has a bridge mode that effectively disables the router, that would most likely be the best option to pursue.

         

        If your Sagemcom device does not have a bridge mode, you will need to configure your R8000 as an access point.  For reference see here:  https://kb.netgear.com/26765/Which-features-are-disabled-on-my-NETGEAR-router-when-it-is-set-to-AP-Mode
